Specification of Letters Patent.

Patented July 19, 1910.

Application led April 5, 1910. Serial No. 553,490.

To all whom it may concern:

Be it known that I, BoLEsLAv DLoUii', a Subject of the Emperor ofAustria-Hungary, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new andImproved Smokeless Muffler, of which the following is a full, clear, andexact description.

An object of the invention is to provide a new and improved muffler,arranged to deaden the noise of the exhaust gases and to deprive thesame of smoke.

For the purpose mentioned, use is made of a casing having a zigzagpassage forthe exhaust gases from the engine, and liquid jets for thegases, to condense the saine and deprive the gases of smoke.

A practical embodiment of the, inventio is represented in theaccompanying draw.- ings forming a part of this specification, in

. which similar characters of reference indicate corresponding parts inboth views.

Figure l is a cross section of the improved smokeless muiiler as aplied, and Fig. 2 is a longitudinal section oi) the muliler.

The casin A, is preferably made cylindrical, and is connected near oneend with the exhaust pipe B- of an internal combustion engine, andwithin the casing A are arranged transverse baliie plates C, providedwith apertures D, D located alternately at the-bottom and top ofsuccessive plates C,

to provide a zigzag passage through the casing A, for the exhaust gasesto travel through from the inlet at the pipe B to the outlet E at theother end of the casing A. By the use of the baiileplat-es C, the noiseof the exhaust gases is gradually deadened and the baile plates .C formWithin the casing A se arate compartments, each of which is provi ed atthe top with a spraying nozzle F, connected by a branch pipe G with awater supply pipe G, connected with a pump H, having its suction pipe Iextending into "a reservoir J, connected by a pipe K with the bottom ofthe muliler casing A. The pump H may be thelpump usually employed forcirculating water through the cylinder jacket to keep the enginecylinder cooled.

When the engine is in use and the pump H is running, then ,the exhaustgases from the engine are passed through thepzigzag passage in the casinA, and water is pumped by the pump into the nozzles. F

by Way of the pipe G. The water passing into the nozzles F is sprayed bythe latter ento the exhaust gases passingl through the casing A, so thatthe gases are deprived of the smoke, and the Water flows along the,bottom of the casing. into the pipe K, to return to the reservoir J,from which the Water is drawn bythe pump H. Any oil,.

zag passage in the casing A, and the smoke and vapors are condensed bythe sprays of water, so that the gases finally escaping atv the outlet Eare practicall noiseless and free of obnoxious smoke 'an smell.

The muffler described is exceedingly serviceable for use on automobiles,motor boats and other vehicles using gasolene, or other internalcombustion engines.

Having thus described my invention, l claim as new and desire to secureby Letters Patent 1. A smokeless muffler, comprising a casin having aninlet and an outlet for the ex aust gases, battle plates in the casin toprovide a zigzag passage for the gases w ile passing from the inlet tothe outlet, and nozzles located between adjacent baiiic plates andconnected with a liquid supply for spraying a liquid onto the gasesduring their passage through the casing.

2. A smokeless muffler comprising 'acasing having an inlet and an outletfor the exhaust gases from an engine, battle plates in 'the said casingto provide a zigzag passage for the exhaust gases, nozzles in the top ofthe' casing intermediate adjacent baffle plates, a pump connected withthe said nozzles, and a reservoir connected with the said casing te'receive tlie water from the latter, the suction pipeof the said pumpextending into the reservoir..

3. A smokeless muliier, comprising a casing having an inlet and anoutlet for the ex-` haust gases from an engine, ba-file plates in thesaid casing to provide a zigzag passage for the exhaust gases, nozzlesin the to of the casing intermediate ad'aoent ba ie plates, 'a pumpconnected with t e said nozzles, a reservoir connected with the saidcasing to receive the yWater from the latter, the suction pipe ofthesaid pump extending int-o the reservoir, and drainin means on thereservoir for draining ooi and other extraneous matter.

1. A smokeless muiileil, comprising a casing, an inlet pipe for exhaustgases connected with one en d of said' casing, and an outlet at'theother end, a series-of transveise bafiie plates Within the casing andforming with the casing separate compartments, each baffle platebeingprovided with apertures located alternately at the bottom and top ofsuccessive glates, a spraying nozz'le at the top ofeac compartment, anda vs fater supply pipe connected with said nozz es.

5. A smokeless mur, comprising a easing through which the exhaust gasespass, spraying evices .in the casing, a'reservoir connected with theoasin to receive the Waterjfrom the latter, am? means for forcing thewater from the reservoir to said spraying devices.

6. A smokeless ing having an inlet an mller .comprising a casd an outletfor the eeaoeo4 exhaust gases, means for roviding a zig-` f zag passagefor the :gases w iile passing from the inlet to the outlet,.means for'spraying a liquid onto the gases during ,the passage through thecasing, a reservoir connected with the casing to receive the water fromthe latter, and a pump connected withl the' reservoir. 7 A smokelessrnuler, comprising a casin having an inlet and an outlet for the eX austases, baiiie plates in the said casing,
